Statistical Inference of Minimum Rank Factor Analysis
Psychometrika, 2002For any given number of factors, Minimum Rank Factor Analysis yields optimal communalities for an observed covariance matrix in the sense that the unexplained common variance with that number of factors is minimized, subject to the constraint that both the diagonal matrix of unique variances and the observed covariance matrix minus that diagonal matrix

On the Statistical Treatment of Residuals in Factor Analysis
Psychometrika, 1962A method for estimation in factor analysis is presented. The method is based on the assumption that the residual (specific and error) variances are proportional to the reciprocal values of the diagonal elements of the inverted covariance (correlation) matrix. The estimation is performed by a modification of Whittle's least squares technique. The method

Statistical analysis of nonlinear factor analysis models
British Journal of Mathematical and Statistical Psychology, 1999This paper presents a Bayesian analysis of a general nonlinear factor analysis model. Both the non‐informative and conjugate prior distributions are considered. A hybrid algorithm that combines the Metropolis‐Hastings algorithm and the Gibbs sampler is implemented to produce direct estimates of the latent factor scores and the structural parameters ...

Assessment of the Controlling Factors in Turbo Flotation by Statistical Analysis
Coal Preparation, 2000TurboFlotation is a new flotation system that has the advantage of large throughput per unit volume and low fluid inventory. The influence of process and design parameters on the performance of the TurboFlotation system as applied to coal flotation has been studied and statistical models developed to predict the performance of the system under various ...

Multistructure Statistical Model Applied To Factor Analysis
Multivariate Behavioral Research, 1976A general statistical model for the multivariate analysis of mean and covariance structures is described. Various models, such as those of Bock and Bargmann; Joreskog; and Wiley, Schmidt and Bramble, are special cases. One specialization of the general model produces a class of factor analytic models.

Statistical distribution of factors and factor images in factor analysis of medical image sequences
Physics in Medicine and Biology, 1998From a time or energy image sequence, factor analysis of medical image sequences (FAMIS) estimates factors, representing kinetics or spectra in a given physiological compartment, and associated factor images, showing the compartments corresponding to each curve.

Statistical Approaches to Suicidal Risk Factor Analysis
Annals of the New York Academy of Sciences, 1986Suicide research is a particularly difficult area primarily because of the base rate problem and inadequate case finding. Traditional item-analytic and multiple regression or discriminant function data-analytic methods in suicide research are criticized on several technical grounds, including capitalization on chance, failure to cross-validate, and ...

Effect of factors on RFID tag readability-statistical analysis
2009 IEEE International Conference on Electro/Information Technology, 2009Radio frequency identification, or RFID, is a generic term for technologies that use radio waves to automatically identify individual items. This paper examines the effect of different factors such as distance to the tag from antenna, height and position of antenna, effect of metals, and interference from other sources on readability of the tag ...
